# This script computes the various flags needed to run GNU C++ testsuites
|
|
# (compiler specific as well as library specific). It is based on
|
|
# the ./mkcheck.in, which in the long will be removed in favor of a
|
|
# DejaGnu-base framework.

# Synopsis
|
|
# * tests_flags --compiler build-dir src-dir
|
|
#
|
|
# Returns a space-separated list of flags needed to run front-end
|
|
# specific tests.
|
|
#
|
|
# * tests_flags --built-library build-dir src-dir
|
|
# * tests_flags --installed-library build-dir src-dir install-dir
|
|
#
|
|
# Returns a colon-separated list of space-separated list of flags,
|
|
# needed to run library specific tests,
|
|
# BUILD_DIR:SRC_DIR:PREFIX_DIR:LTCXX:LIBS:LTEXE:CXX:CXXFLAGS
|
|
# the meaning of which is as follows:
|
|
# BUILD_DIR build-dir
|
|
# SRC_DIR src-dir
|
|
# PREFIX_DIR install-dir (meaningful only with --installed-library)
|
|
# LTCXX libtoolized command to compile a C++ program
|
|
# LIBS flags to pass to the linker
|
|
# LTEXE libtoolized command to run a compiled C++ program
|
|
# CXX which C++ compiler is being used
|
|
# CXXFLAGS special C++ flags used
|
